To It chain it many concern:

Be it known that I, MAmsoN F. BATES, a citizen of the United States, residing at Lansing, in the county oflnghain, State of Michigan, have invented certain new 'and useful improvements in VVater-Coolers; and l do declare the following to be a full, clear,- and exact description ot the. invention,-such. as will enable others skilled in the art to which it appertains to make and use thesarne, reterenee being had to theaccoinpanyirig drawings, and to the figures of reference marked thereon, which form a part of this specification. l 4 '-lfhis invention relates to a water-cooling device for cxplosive-engines; and it consists in the const-ruction and arrangeinent of parts hereinafter fully set forth-and claimed.

The object of the invention is to produce a cooler of the class describedwherein the arrangeinenti is such as to vallow facility of movement of the} connectedparts without danger of opening the joints between the tubes and heads into which theyz'trc coupled and to allow or. the ready removal otany one 1 of a plurality. of divisions ofthe cooling-tubes [or the purpose of repair in case said tubes be come injuredby an accident or are damaged by freezing. v I The above objcct'is attained'by the struc ture illustrated in the accompanying drawings; in which- I Figure 1 is an end. elevation of a cooler enibodying iny ii-n'ention, a part of t he metal casing or hood being broken away toshow the ends 01 the t1o-bolts,wh|ch connpctt'hc heads of the cooler with the upper-and lower watersections, liig. :2 is an end elevation-with a v portion ot the hood in section. 40

Fig. 3 is an enlarged vertical section throughone ot the divisions ofv the cooler as on line 1% Bot-Fig.1] Fig. 4 is a longitudinal section through the upper and lower heads of a. co ole1 'sectitm. Fig. 5 is'a fragmentary view in elevation,

showing a niodilivd form of attaching the heads to the water-sections. Fig. 6 Iis a fragmentary View in section as on line 6 6 of Fig.5.

like apertures 5 through the front wall thereof. A cooler-division comprises an upper head 6-and a lower head 7, into which are connected the opposite -ends of a series of Acooler may be composed of as many divi- .of into. a tapped boss 10 on the innertace of the back wall of the upper section and by passing a tie-bolt 12 through the'lower head 7 in like manner and screwing it intothe boss 13 on the wall of the lower section '-1 the outer ends of said bolts 9 and 12 passing through the heads 6 and (and receivingthc nuts '11 and '11, respectively. To make a tight joint between the heads and the watersections, a gasket 1-5 1s placed between the inner endsof the heads 6 and 7 and the faces of the 'upper and-lower sections, against which said heads bear around the respective openings 3 and 5,3and a gasket 16 is placed between each'of the nuts 11 and 1-4 and the outerendsof the heads 6 and'7. By this arrangelnent 11' provide for facility of moveinent between the component parts of the cooler without liability of opening the joints, enabling the parts to spring and return again to their normal position without inj ury, whereas a cooler formed by soldering the tubes into the heads, as connnonly practiced;

is caused to leak-should'the parts become It will also abled torcadily repair a division of the cooler whose tubes b'econie broken by removing the nuts 11 and 11 lroin the tie-bolts t) and 1'2v without disturbing-any other portion of the cooler.

Communicating with the reservoir is an inllmv-pipe 17, and leading l'roni the lower water-section 4 is an outllmr-pipe 15'. Those .pipcs in-practice are connected with a suit able pump (not shown) or other device for maintaining a -'c'irculatio1.i of water through the cooler, and through the wat er-space ol". the engine-cylinder. Upon the tubes 8 are the ordinary radiating rings 19. Upon the tront of the heater are suitable fastening devices 20 for the purpose ol'inaintaining the hood '31 in position. Itwill :be noted that the water passes from the reserv: \ir downwardly through the water-section 2 into the upper heads t3, thence dow-in'va'rdly through the tubes 8 into the lower headsi, them-o into the lower water-section throughthe pipe 18 back to the pu'inp'or sduice of supply.

In constructing "coolers {for small engines wherein the heads ,6 and? would be of cornparativelysmall diameter it may be found I expedient to employ the construction shown in Figs. 5, and (i for connecting the heads with thewater-sections, which construction consists in employing a clip 22, having projecting end portions 23,-=Which bear against the ends of thewat'er-heads 6 and are held in place by-a tiebolt 24, which passes centrally rangement two heads are held in place by one through said clip. and between the heads 6, its" inner end screwing into the wall of the water-section 2, as shown at 25. By this artie-bolt, and uthe tie-bolt is permitted to pass between the'heads instead of through one of them, thereby obviating a reduction in the water-space of the'head incident to the passage of the tie-bolt therethrough. A nut 26' is screwed .onto the end of the bolt 24 for the purpose ofdrawing the. heads tightly into-- place.

Having thus fully set forth my invention,

- what I claini as new, and desire'tozsecure by Letters Patent, -is v 1.. In a water cooling'device, the combination with the reservoir, of the upper watersection' communicating therewith and havin "watlencirculatory openings through the we thereof, ,thelower water-section also-having water-circulatory openings through the wall thereof, the cooler-divisions comprising the upper and-lower heads connectedbya series of 1 vertical tubes said heads being openat their inner'ends, and means for remova said heads to the upper and lower water-sectionsrespectivelyover said openings in said water-sections" to establish communicationbetween 'said sections through said heads and tubes.

-2. Ina water-cooling1 device, the combination'with the upper and lower water-sec:

arge area, of the cooler-ditioiis of relatively of said visions comprising the upper and lower hol 10w heads of relatively small area connected by a plurality of vertical tubes and communicating with said Water-sections through 4 5 openings equalin in diameter the diameter eads, a'ncI the tie-bolts" passing longitudinally through said heads and secured insaid sections respectively to detachably couple the heads and sections together. 3. In a water-cooler, the combination with "the up er water-section having openings in the. wal thereof, a. pluralityot upper heads open at their ends connnunicatin iride end- 'ently with said. up er section t oug the openings therein, a ower water-section havopenings in thewallthereof, a plurality 1n of lower heads open at. their ends com-municating independently with said lower section through said openings, vertical tubescon-I necting the upper and lower heads in pairs, tie-bolts passing through the upper and lower heads and screwing into the-upper and lower sections res'ectively, nuts upon theouter ends of said olts and gaskets between the heads and sections, 1 and between sai'd nuts and the ends of said heads.

4:. In a water-cooling device, the coinbina 'tion with the reservoir, oi'the upper water- 'section communicating therewith, the lower water-section. said water-sections having openmgs 1n their side walls, the cooler-divi-- sions comprising 'the up er and lowerheads connected bya series 0 vertical tubesand open at their ends, and tie-bolts for reinovly securing said heads ,to-the upper and. lower water-sections respectively to establish communication between "said sections tion inthe presence of two-witnesses. r
